Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 30
Sanskrit:
इतीन्द्रानुचरैर्ब्रह्मन् धर्षितोऽपि महामुनि: ।यन्नागादहमो भावं न तच्चित्रं महत्सु हि ॥ ३० ॥
ITRANS:
itīndrānucarair brahmandharṣito ’pi mahā-muniḥyan nāgād ahamo bhāvaṁna tac citraṁ mahatsu hi
Translation:
O brāhmaṇa, the followers of Lord Indra had impudently attacked the saintly Mārkaṇḍeya, yet he did not succumb to any influence of false ego. For great souls such tolerance is not at all surprising.
